Privacy

The short version

• The numbers you type into the calculator never leave your browser.
• GougeProof has no accounts and asks for no name, email address or phone number.
• It sets no cookies.
• It has no ad pixels, session replay, chat widgets or tag managers.
• We never sell or pass on your details.

Your deal numbers

The calculator runs in your browser. The prices, rates, fees and trade-in figures you type are worked out on your own device and are not sent to GougeProof or to anyone else. There is no form that submits them and no page on the site that receives them.

Share links

A share link holds your deals after the # in its address. A browser never sends that part to a website, so it does not reach GougeProof, our host’s logs or our counts, and it is not passed along when you click a link to another site. The link is read in your browser when it is opened. Anyone you give the link to can read the numbers in it, so share it only with people you want to see them.

What stays in your browser

The site saves four things in your browser’s local storage, on your device only, and never sends them anywhere:

• your deals, so they are still there when you come back (gougeproof.sheet);
• the payment check’s own boxes (gougeproof.check);
• your light or dark pick, if you used the switch (gougeproof.theme);
• whether you asked for the full sheet instead of the simple view (gougeproof.view).

Clearing your browser’s site data for gougeproof.com removes all four. If your browser blocks storage, the site still works and simply forgets between visits.

Cookies

GougeProof sets no cookies on your visit.

Counting visits

We count visits with PostHog, a service run by PostHog Inc. in the United States. It is set up to see as little as it can:

• It counts a short, fixed list of moments, such as a page being opened.
• It never records what you type: no prices, rates, trade-in values, states, counties or ZIP codes.
• It sets no cookie and saves nothing in your browser.
• It does not keep your IP address, and the addresses it records have the part after the # and any query removed.
• It records no sessions, no clicks on the page and no heatmaps, and it builds no profile of you.

The counts reach PostHog through our own domain. A blocker that stops them breaks nothing on the site.

Global Privacy Control and Do Not Track

If your browser sends Global Privacy Control, or the older Do Not Track signal, GougeProof treats both as a request not to be counted. Once counting is on, the counting code is never loaded for you at all, and the footer says so. The footer of every page tells you which signal your browser sent. Today it reads:

• Your browser sent Global Privacy Control, so GougeProof isn't counting this visit.
• Your browser sent Do Not Track, so GougeProof isn't counting this visit.
• We count visits anonymously: no cookies, and never what you type.

Who else is involved

• Vercel hosts the site. Like any host it keeps ordinary request logs, which include the address of the page asked for, the time, your IP address and your browser’s name. We do not use them to follow individual visitors. They never contain a share link’s numbers, because those come after the #.
• PostHog counts visits, as described above, once it is switched on.
• Our domain registrar forwards mail sent to our contact address.

No other company runs code on the site. The font is served from our own domain. Nothing on the site follows you from one website to another, and no one else collects information about you through it that we know of.

Offers and links to other sites

There are no offers on GougeProof yet. The few links that leave the site go to pages run by others, and their own privacy terms apply there. We never sell or pass on your details. If we ever add an offer, your calculator numbers will not be put into its link.

If you email us

If you write to support@gougeproof.com, we receive your email address and whatever you put in the message. We use it to reply and to fix what you reported. We do not add it to a list. The “Report a wrong number” link asks for the page, the number and a source, and for nothing personal.

Children

GougeProof is about buying a car with a loan and is meant for adults. It does not ask anyone, including a child, for personal details, and it does not knowingly collect them.

Changes to this page

When the site starts counting visits, or anything on this page stops being true, this page is changed in the same release. The date at the top is the day it last changed. Questions: contact.
